Abstract
The utility model discloses a car sheet metal component damping nut has: a cooperating bolt and nut; the connecting piece is connected with the sheet metal part through a bolt and a nut, and the rubber sheath wraps the nut; the end surface of the rubber sheath is contacted with the sheet metal part; the vibration damping cushion is arranged between the connecting piece and the sheet metal part, and the bolt penetrates through a through hole of the vibration damping cushion; the boss is arranged on the through hole of the vibration reduction cushion, and the boss penetrates through the connecting hole of the sheet metal part, so that the vibration reduction effect can be achieved, the sheet metal part can be conveniently assembled, and welding or press riveting is not needed.
Description
Technical Field
The utility model belongs to the technical field of the car, especially, relate to a car sheet metal component damping nut.
Background
At present, two fixing modes for assembling nuts on sheet metal parts are provided, one mode is a nut welding mode, and the other mode is a nut pressing and riveting mode.
In the process of implementing the present invention, the inventor finds that the prior art has at least the following problems: the nut and the sheet metal are processed into a whole, alloy components are added in the middle after contact surfaces of the two metals are melted at high temperature, the two metal components are mixed together and cooled, the interior of the contact position is acted by molecular force, and the strength is generally higher than that of a parent body; the connected nut can deform due to high temperature in the welding process and cannot be detached; in addition, the common welding method cannot be used for some active metals; the method of riveting the nut is used, one end of the nut is provided with embossing teeth and a guide groove nut, the nut is embedded into a position matched with a sheet metal piece through pressure, knurling is arranged on a contact surface, the sheet metal piece is mutually extruded, and the strength depends on the strength of the nut and the sheet metal material; when the nut is subjected to shear stress, if the strength of the nut is not enough, the nut can be damaged by shearing and fails, and if the strength of the parent sheet metal is not enough, the nut can be plastically deformed and crushed to fail; both the welding nut mode and the pressing rivet nut mode are in rigid connection, and the effects of reducing vibration and preventing bolts from loosening cannot be achieved.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a car sheet metal component damping nut that can play the damping effect, be convenient for assemble again to sheet metal, need not weld or press and rivet is provided.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: a kind of car sheet metal part damping nut, have:
a cooperating bolt and nut; the connecting piece is connected with the sheet metal part through the bolt and the nut;
the rubber sheath wraps the nut; the end face of the rubber sheath is in contact with the sheet metal part;
the vibration damping cushion is arranged between the connecting piece and the sheet metal part, and the bolt penetrates through a through hole of the vibration damping cushion; the through hole of the vibration reduction cushion is provided with a boss, and the boss penetrates through the connecting hole of the sheet metal part.
The boss extends into the rubber sheath.
And the surface of the rubber sheath, which is in contact with the metal plate, is provided with rubber anti-skid lines.
And rubber anti-skid grains are arranged on the contact surface of the vibration-damping soft pad and the metal plate.
One of the technical scheme has the advantages or beneficial effects that the vibration reduction effect can be achieved, the sheet metal part can be conveniently assembled, and welding or press riveting is not needed.
Drawings
Fig. 1 is a schematic structural view of a vibration-damping nut for an automobile sheet metal part provided in an embodiment of the present invention;
the labels in the above figures are: 1. bolt, 2, connecting piece, 3, damping cushion, 4, sheet metal component, 5, nut, 6, rubber sheath.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, an automobile sheet metal part damping nut has:
a cooperating bolt and nut; the connecting piece is connected with the sheet metal part through a bolt and a nut;
the rubber sheath wraps the nut; the end surface of the rubber sheath is contacted with the sheet metal part;
the vibration damping cushion is arranged between the connecting piece and the sheet metal part, and the bolt penetrates through a through hole of the vibration damping cushion; the through hole of the vibration damping cushion is provided with a boss which passes through the connecting hole of the sheet metal part.
The boss extends into the rubber sheath.
The surface of the rubber sheath contacting the metal plate is provided with rubber antiskid lines. The contact surface of the vibration-damping soft pad and the metal plate is provided with rubber antiskid lines.
With the exposed part of nut with the rubber protective sheath parcel, increase the life of nut, the nut has corresponding rubber anti-skidding line with the panel beating contact surface, prevents that nut and bolt synchronous revolution when erection equipment, has simultaneously one with bolt assorted damping cushion, add with the fitting surface of bolt on, the cushion face also has anti-skidding line with the panel beating contact surface, prevents that the cushion is rotatory. The nut protective sheath is fixed on the sheet metal component with the cooperation of damping cushion, under the environment of vibration, plays the damping guard action to nut and bolt, can receive the moulding extrusion of warping of rubber sheath and damping cushion during bolt fastening connection spare simultaneously, prevents effectively that the bolt from becoming flexible.
After the structure is adopted, the vibration reduction effect can be achieved, the assembly on a sheet metal piece is facilitated, and welding or riveting is not needed.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without modification to the method and technical solution of the present invention, or the present invention can be directly applied to other occasions without modification, all within the scope of the present invention.
